From:             
Operating system: Windows 7

Bug description:Internal class reference resets the attribute

Description:
------------
I know it is uncommon usage of reference but i have  a pretty complicated 
equation 
inside a function, and i referenced a value like $a &= %this->bla...
It is easier to write $a instead $this->a... in case you have a BIG
equation...

 And imagine my surprise when i saw that the value was not set... my guess
is 
that 
this code somehow screws the internal references....  Searched here and
nothing 
showed up for classes... just run the script it should  output the error...

don`t 
know about UNIX OP but i doubt it is different... 
here is how i get the error:

class a {
    
   public $t;
   function buga(){
       $this->t = 'buga';
   }
   function bla(){
       
       $b &=$this->t;
       echo $b;
   }
}
$a= new a;
$a->buga();
$a->bla(); //this outputs Notice: Undefined variable: b in C:\...\test.php
on 
line XX

I use Wamp Server package 2.0f latest version... Hope i was right about
it... if 
not, Sorry...

Test script:
---------------
class a {
    
   public $t;
   function buga(){
       $this->t = 'buga';
   }
   function bla(){
       
       $b &=$this->t;
       echo $b;
   }
}
$a= new a;
$a->buga();
$a->bla(); //this outputs Notice: Undefined variable: b in C:\...\test.php
on line XX

Expected result:
----------------
This should output just bla

Actual result:
--------------
But it outputs a notice... and no variable...
this outputs Notice: Undefined variable: b in C:\...\test.php on line XX
